[Bug 523970] Re: color scale in the ranking tab can collapse to all grey

 

>two sliders should always remain

Yes

>one can be white and the other black.

No.

I have three sliders: white, grey, black. Then I move the white slider
to the right until it disappears (strange idea, I admit, but I did it
incidentally). I'm left with two sliders, one grey and one black. I
cannot have any white in the scale anymore.

Bug description:
Low importance.

- open a graph with an attribute "weight" on edges, of type "float".
- click tab ranking, edge, choose "weight".
- click in the middle of the color scale (that goes from white to black). A white triangle (a slider) appears.
- move the leftmost triangle to the right until it disapears
Now the color scale goes from grey to black, I see no way to restore it from white to black.

Those steps can be repeated, mirrored (right to left) to make black disappear. One then gets a uniformly grey colorscale, not really useful ;-)
